The plant serves a population of 849 and operates under the regulatory framework of the United States Clean Water Act, which requires advanced treatment for discharges to sensitive waters. The plant employs advanced treatment processes, achieving a higher level of pollutant removal than secondary treatment. Its designed capacity is 132.49 units, with a current discharge volume of 113.56 units, indicating it operates below capacity. As a coastal facility within 10 km of the Atlantic Ocean, the plant's effluent must meet stringent standards to protect marine ecosystems. The treated wastewater is discharged into local waterways that drain into the Long Island Sound or the Atlantic Ocean. This region supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's advanced treatment helps minimize nutrient loading and protects downstream water quality in this ecologically sensitive coastal area.

The plant discharges into the watershed of the Long Island Sound, a large estuary that connects to the Atlantic Ocean. The Sound supports diverse marine life, including shellfish, finfish, and migratory birds. Advanced treatment at this plant reduces nitrogen and other pollutants, helping to prevent eutrophication and maintain the ecological health of this important coastal ecosystem.
